Confidence Analysis

Score: 57/100

Low-confidence STS candidate – may warrant review. Two tankers (MEGION and NOYABRSK) maintained close proximity (min 382m, avg 386m) for 34 minutes. Both vessels were slow-moving (avg speeds 0.3 and 0.1 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Ust-Luga Terminal Complex, a known STS activity area.

Confidence Analysis

Score: 72/100

Moderate-confidence STS candidate. Two tankers (NOYABRSK and MEGION) maintained close proximity (min 382m, avg 388m) for 91 minutes. Both vessels were slow-moving (avg speeds 0.0 and 0.3 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Ust-Luga Terminal Complex, a known STS activity area.
